As the advanced network features egress IP, egress firewall, egress router and multicast will be affected by the migration in different ways. We shall provide instructions to users on how to check if these features are enabled in their clusters as part of the pre-migration check.

The check can be done by querying the metrics:
1. From the OpenShift Container Platform web console, navigate to Observe -> Metrics.
2. In the Expression box, add the following queries, and then click Add:
   - for egressRouter
     network_attachment_definition_instances{networks="egress-router"} > 0
   - for egressFirwall
     sdn_controller_num_egress_firewalls
   - for egressIP
     sdn_controller_num_egress_ips
   - for multicast
     sdn_controller_num_multicast_enabled_namespaces

3. Click Run queries.
